RX PubMed=22187461; DOI=10.1073/pnas.1117648108; RA Pathare G.R., Nagy I., Bohn S., Unverdorben P., Hubert A., Korner R., RA Nickell S., Lasker K., Sali A., Tamura T., Nishioka T., Forster F., RA Baumeister W., Bracher A.; RT "The proteasomal subunit Rpn6 is a molecular clamp holding the core and RT regulatory subcomplexes together."; RL Proc. Natl. Acad. Sci. U.S.A. 109:149-154(2012). CC -!- FUNCTION: The proteasome is a multicatalytic proteinase complex which CC is characterized by its ability to cleave peptides with Arg, Phe, Tyr, CC Leu, and Glu adjacent to the leaving group at neutral or slightly basic CC pH. The proteasome has an ATP-dependent proteolytic activity. CC -!- SUBUNIT: The 26S proteasome consists of a 20S proteasome core and two CC 19S regulatory subunits. The 20S proteasome core is composed of 28 CC subunits that are arranged in four stacked rings, resulting in a CC barrel-shaped structure. The two end rings are each formed by seven CC alpha subunits, and the two central rings are each formed by seven beta CC subunits. The catalytic chamber with the active sites is on the inside CC of the barrel (By similarity). Interacts with Rpn6. {ECO:0000250, CC ECO:0000269|PubMed:22187461}.

Nucleus {ECO:0000250}. CC -!- SIMILARITY: Belongs to the peptidase T1A family. {ECO:0000255|PROSITE- CC ProRule:PRU00808}.
